EmailBundle
Store multiple
Use the message count and indexed access methods to retrieve individual
emails for inspection, processing, saving, or sending.
Locate a specific email in the collection when application logic needs
to find a matching message.
Sort the bundle by date, sender, recipient, or subject to organize
messages before processing or display.
Remove individual messages by object or index, or clear the entire
bundle when the collection is no longer needed.
Serialize the bundle to XML and reload it later, or load task results
that return an email bundle.

EmailBundle Class Overview.
Hold, search, sort, remove, save, and reload groups of email messages.
EmailBundle is a container for multiple
Email objects. It is commonly returned by mail-related
operations and can also be built manually by adding individual email
messages. The class provides a simple way to work with groups of messages:
retrieve emails by index, search for a matching email, sort by common email
fields, remove messages, clear the bundle, and serialize or reload the
collection as XML.
Email collection
Email objects together after
receiving, loading, filtering, or manually building a message set.
Retrieve messages
Search within the bundle
Sort messages
Remove or clear emails
Save and reload
Email objects, loop from
0 to MessageCount - 1, retrieve each message with
EmailAt, and then inspect, save, sort, remove, or process each
email as needed. Use EmailBundle for the group and
Email for the individual message contents.
Object Creation
use Chilkat2;
my $emailBundle = Chilkat2::EmailBundle->new;
# or set properties (and RaiseError) at creation:
# my $emailBundle = Chilkat2::EmailBundle->new(VerboseLogging => 1, RaiseError => 1);Creates the object. The optional pairs set writable properties (and RaiseError) in order, as if set one by one; an unknown or read-only name croaks. use Chilkat2; loads every class; the Chilkat2/EmailBundle.pm file holds only this class's documentation (perldoc Chilkat2::EmailBundle).
Perl frees the object when its last reference goes (undef $emailBundle, or the variable going out of scope); there is nothing to close. Objects returned by methods are independent and freed the same way. The class may be subclassed (use parent -norequire, 'Chilkat2::EmailBundle';): an object is a blessed hash reference whose hash is free for the subclass's own fields.
When false (the default), a method that fails returns false (or undef), and the reason is in LastErrorText. When true, it dies with a Chilkat2::Error instead, as DBI does with its RaiseError. Objects returned by a method inherit the value of the object that returned them.
Errors
A Chilkat2::Error stringifies to the failed call's full LastErrorText, and has the methods text, class ('Chilkat2::EmailBundle'), method (the method name) and object. Methods that look something up and find nothing return undef without dying (each such method says so), methods that answer a question (HasMember, IsUnlocked, ...) return a plain boolean, and property reads and writes never fail for Chilkat reasons.
Misuse always croaks, with your file and line, whatever RaiseError is: a wrong number of arguments, a reference or undef where a string or number is expected, an object of the wrong class, an out-of-range integer, a string containing a NUL character, a wide character in a byte string, or a write to a read-only property.
Strings are Perl character strings in both directions (length, regexes and :encoding layers see characters); binary data (BinData) is a byte string. Unlocking: call Chilkat2::Global->new->UnlockBundle('...') once at startup.
Properties
DebugLogFilePath
my $strVal = $emailBundle->DebugLogFilePath;
$emailBundle->DebugLogFilePath($strVal);
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
LastErrorHtml
my $strVal = $emailBundle->LastErrorHtml;
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
my $strVal = $emailBundle->LastErrorText;
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
my $strVal = $emailBundle->LastErrorXml;
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
my $boolVal = $emailBundle->LastMethodSuccess;
$emailBundle->LastMethodSuccess($boolVal);
Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
MessageCount
my $intVal = $emailBundle->MessageCount;
Returns the number of Email objects currently contained in the bundle.
Valid zero-based indexes range from 0 through MessageCount - 1.
VerboseLogging
my $boolVal = $emailBundle->VerboseLogging;
$emailBundle->VerboseLogging($boolVal);
If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version
my $strVal = $emailBundle->Version;
Methods
AddEmail
# $success is true or false
my $success = $emailBundle->AddEmail($email);
Adds an independent copy of the Email object in $email to the end of this in-memory bundle.
The bundle does not retain a reference to $email and does not take ownership of the supplied object. Changes made to $email after this method returns do not affect the copy stored in the bundle, and changes to the stored copy do not affect $email.
The same Email object may be added more than once. Each call adds another independent copy and increases the MessageCount property by one.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
Clear
Removes and discards all emails from this in-memory bundle.
After this method returns, MessageCount is 0. No messages are deleted from any mail server.
Returns the object, so calls can be chained.
topEmailAt
# $email is a Chilkat2::Email
# $success is true or false
my $success = $emailBundle->EmailAt($index, $email);
Copies the email at the zero-based index in $index into the Email object in $email.
Valid indexes range from 0 through MessageCount - 1. The first email is at index 0.
$email receives an independent copy. Changes made to $email do not modify the email stored in the bundle.
Note: This is an in-memory operation and does not communicate with a mail server.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
FindEmail
# $email is a Chilkat2::Email
# $success is true or false
my $success = $emailBundle->FindEmail($json, $email);
Finds the first email in the bundle whose MIME header field matches the search criteria specified by the JsonObject in $json.
At this time, a search may specify only one MIME header field. Use the following JSON format:
{
"header": {
"name": "Subject",
"value": "Dinner on Wednesday?",
"caseInsensitive": true
}
}
header.name specifies the MIME header field name, and header.value specifies the complete field value to match. The field value must match exactly; this is not a substring, wildcard, or regular-expression search. Set header.caseInsensitive to true for a case-insensitive comparison or false for a case-sensitive comparison.
When a match is found, $email receives the first matching email.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
GetXml
my $str = $emailBundle->GetXml();
Serializes the entire email bundle to Chilkat XML and returns the XML document as a string.
The XML contains the bundle and its individual Email objects. It can be loaded into another EmailBundle by calling LoadXmlString.
This is Chilkat's XML representation of an email bundle; it is not an RFC 822/MIME message.
Returns undef on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
LoadXml
# $success is true or false
my $success = $emailBundle->LoadXml($path);
Loads an email bundle from the local filesystem path specified by $path. The path may be absolute or relative; a filename alone refers to a file in the current working directory.
The file should contain Chilkat email-bundle XML previously produced by SaveXml or GetXml.
The emails loaded from $path are appended to the emails already in the bundle. Existing emails are not removed or replaced.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
LoadXmlString
# $success is true or false
my $success = $emailBundle->LoadXmlString($xmlStr);
Loads an email bundle from the Chilkat XML string in $xmlStr.
The XML is typically obtained from GetXml or read from a file created by SaveXml.
The emails loaded from $xmlStr are appended to the emails already in the bundle. Existing emails are not removed or replaced.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
RemoveEmail
# $success is true or false
my $success = $emailBundle->RemoveEmail($email);
Removes the first email in this in-memory bundle that matches $email.
Chilkat first searches for an email having the same UIDL as $email. If no email with a matching UIDL is found, it searches for the first email having the same Message-ID header field value. Only the first matching email is removed.
$email may be an independent copy obtained from EmailAt.
Note: This method changes only the local bundle. It does not delete a message from a POP3 or IMAP server.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
RemoveEmailByIndex
# $success is true or false
my $success = $emailBundle->RemoveEmailByIndex($index);
Removes the email at the zero-based index in $index.
Valid indexes range from 0 through MessageCount - 1.
Note: This method changes only the local bundle. It does not delete a message from a mail server.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
SaveXml
# $success is true or false
my $success = $emailBundle->SaveXml($path);
Serializes the bundle and each contained Email to Chilkat XML, then writes the XML document to the local filesystem path specified by $path. The path may be absolute or relative; a filename alone writes to the current working directory.
Reload the saved bundle by calling LoadXml. Use GetXml when the XML is needed in memory rather than in a file.
The saved file is a Chilkat email-bundle serialization, not an RFC 822/MIME message file.
Returns true on success, false on failure; LastErrorText says why. With RaiseError on, a failure dies with a Chilkat2::Error instead (it stringifies to the LastErrorText); the object remains usable either way.
SortByDate
$emailBundle->SortByDate($ascending);
Sorts the emails in this bundle by each Email object's EmailDate property.
Set $ascending to 1 to sort in ascending order, from oldest to newest. Set $ascending to 0 to sort in descending order, from newest to oldest.
The operation changes the order of the emails in the in-memory collection.
Returns the object, so calls can be chained.
topSortByRecipient
$emailBundle->SortByRecipient($ascending);
Sorts the emails in this bundle by the full value of each email's To header field.
The comparisons are case-sensitive. Set $ascending to 1 for ascending order or 0 for descending order. The operation changes the order of the emails in the in-memory collection.
Returns the object, so calls can be chained.
topSortBySender
$emailBundle->SortBySender($ascending);
Sorts the emails in this bundle by the full content of each email's From header field.
Set $ascending to 1 for ascending order or 0 for descending order. The operation changes the order of the emails in the in-memory collection.
Returns the object, so calls can be chained.
topSortBySubject
$emailBundle->SortBySubject($ascending);
Sorts the emails in this bundle by subject.
Set $ascending to 1 for ascending order or 0 for descending order. The operation changes the order of the emails in the in-memory collection.
Returns the object, so calls can be chained.
